While discussing the 9/11 attacks, in 2004, Paul Hellyer, a former Canadian minister of national defense, posed the question, “Why did airplanes fly around for an hour and a half without interceptors being scrambled from Andrews [Air Force Base] … right next to the capital?” He said: “With a quick-reaction alert they should have been in the air in five minutes or 10 minutes. If not, as a minister of national defense, which in the United States would be the secretary of defense, I would want to say, ‘Why not?’” [22]

His questions are as pertinent today as they were five years ago.
